I wasn't clear: I didn't mean the 'cost' of the clothing, rather people from the upper demographics won't have a problem wearing second hand clothes, but it's unusual to find people from poorer backgrounds buying second-hand. It's a class issue.
Walk through Liverpool these days and you'd be amazed with the clothes people wear (when not wearing sports clothes!) and more importantly the cost of the clothes they wear. They are clearly telegraphing the cost, hence the gratuitous displays of Bling.
I wouldn't wear a D&G suit anyway, but you'd think they were H&M the number of people who do wear them there. It's all about the Bling, which - mercifully - the Swiss don't show-off. (Unless you go to the Carlton bar!)
My experience has been there are lots of good shops in the region which provide high-end ranges (regardless of actual desireability / quality of construction) on the grounds that people buy good clothes here and are not ashamed to wear second hand. What you won't find are D&G t-shirts, Armani sweaters and oh well, it's probably wishful thinking, Polo shirts
Anyway, there are great deals out there, irrespective of whether you'd wear them or not
